PHYSICS PROJECT



PHYSICS PROJECT (Final Exam Grade)

Due 05/15/15

Here is a chance to put your creative skills and science knowledge together. You at last have the opportunity to build a self-propelled car. The device you build should be completely home made. In other words, you should not assemble a kit. Once your device is assembled, you must test it. Look below for more details on the project. The report need to be in ink or typed. Your Final Exam grade will include three parts: the project itself, the lab report, and the presentation of your project in class. If you are able to exempt the final exam, you will get a 100 for the presentation grade but still have to make the project and write the report.

SELF-PROPELLED CAR (one meter size limit) Your self-propelled car should accelerate from a stand still and move at least 1 meter along a level smooth surface (not on a rug). The car should begin to move on its own without any push from you. It may be powered by an electric motor, rubber band, sail or any device attached to the car. It may not be operated via remote control. Your goal should be to make the car go as fast as possible and as far as possible. Do a search for “mousetrap cars” or “self-propelled cars” to get ideas. You must submit test data on the car. Your manipulated variable could involve the car’s weight, design, wheel size, or motor. A graph of your manipulated variable vs. either speed or distance is optional and is a necessary part of a lab report. You need to have 3 trials. You are required to have a data table to report the data.

Laboratory REPORT

You need to complete a Laboratory Report for the project. Follow closely the rubric designed for the testing report. The report should take this format:

I. Title Page (Include name of device, your name, and date)

II. Purpose or Question

III. Hypothesis (in the “if…, then” form)

IV. Materials (list these)

V. Procedure 1) Number each step on a separate line

2) Only include testing steps, not steps in making the device

VI. Results 1) Data from at least 3 trials summarized in a data table

2) Data of dependent and independent variables displayed on a line graph

VII. Conclusions - Do not use I/my and be sure to include the following:

1) Restate your hypothesis

2) Explain whether your data supported the hypothesis and why you thought that

3) Discuss what you learned and how the project could be improved or modified

4) be sure to include all of the vocabulary listed below

Self-Propelled Car Vocabulary- to be used in your conclusion: distance, speed, kinetic energy, potential energy, force, velocity, independent variable, dependent variable, action, reaction, acceleration, mass
